Rare complication of dissection of Valsalva sinus with aorto-left atrial fistula in active aortic valve endocarditis.

ABSTRACT

We present a rare case of dissection of the sinus of Valsalva associated with an aortic annular abscess that perforated into the left atrium. A 61-year-old patient with infective endocarditis underwent emergent operation due to progressive heart failure, in whom echocardiography showed the dissection of sinus of Valsalva with aorto-left atrial communication. Procedure included autologous pericardial patch repair of the dissecting sinus of Valsalva and bioprosthetic valve replacement with a successful outcome. Microscopic examination showed excessive neutrophil infiltration in the aortic valve and annulus without involvement of the sinus of Valsalva.
